Improvement in construction of fly-wheels



UNITED STATES PATENT OFFICE.

JOEL BRYANT, OF BROOKLYN, NEW YORK.

IMPROVEMENT lN CONSTRUCTION OF FLY-WHEELS.

f, Specification forming part of Letters Patent No. 40,011, dated'Septemher 22, 1863 antedated June To all whom it may concern:

Be it known that- I, JOEL BRYANT, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Mode of Using Fly-Wheels in Connection with Portable Machines; and l declare the following to be a full, clear, and correct description of the same-to wit:

The nature of my invention consists in so constructing portable machines such as crushing and grinding mills, corn-shellers, turning-lathes, and all other machines to which my said invention is applicable-with fly-wheels set to run beneath the base or bottom part of said machines, as hereinafter described, so as thereby to add to the force, power, and efliciency of said machines, as hereinafter set forth To enable others skilled in the art to make and use my invention, I will proceed more fully to describe the construction and operation of machines provided with fly-wheels, and using the same in accordance with my improved mode of using fly-wheels in connection with portable machines,'and all other machines to which my said invention is applicable, reference being made to the accompanying drawings, and to the figures and letters marked thereon, and forming a part of this specification-to wit:

Figure l, M, represents a perspective view of my invention or improved mode of using y-wheels WV, in connection with portable or any other machines, M, whose construction and arrangement of parts admit of the ap plication of my invention thereto.

l construct my machines M (irrespective of kind) with a base or bottom part, B, adapted to receive and hold within or beneath the said base B a {1y-wheel, W, set to run on an upright shafl, S, and within or beneath the said base or bottom B, the said upright shaft S being provided with a stop, V, which rests on an anti friction roller-bearing, G, as shown in Fig. 2, the said anti-friction rollerbearing G being made as shown in Fig. 3, resting in its turn on the upper part of the said base B, thus relieving the working paris of said machines M from the weight of the said fly-wheels WV, which run with very little friction, as supported on the bearing G.

Fig. 3 represents and shows the construction of the said anti-friction roller-bearing G, which is made with four antifriction rollers,

Z, running loosely on their axles A, which are firmly connected with a strong ring, R, which is made of sufficient size to receive the said shaf't S and allow it to turn loosely therein. The said anti-friction roller-bearing shaft S, which rests thereon, through the medium of the said stop V, so that the said machines M run with Very little friction, whatever may be the size and weight of the said iiywheels W.

Fig. 4t represents my inventionv as applied to small-sized grinding-mills M.

Fig. 5 shows the way of connecting the fly wheels W with the shafts S.

Fig. 6 represents the aforesaid invention modified by the omission of the said antifriction roller-bearing G, the said shaft S in this case being made to 'est and run ou ordinary bearings at the bottom part of the said hase B of said machines. The said invention may of course be thus modified without materially changing the character of the invention, and, when desirable, I thus modify my said invention or improved mode of using fly-wheels WV in connection with portable or other machines M, as shown in Fig. 6.

The advantages of my invention are, that {1y-wheels W of any desirable size may be used in connection with any machines M which are adapted to their use, as herein proposed, and the weight and size of the said iiy-wheels W may be adapted to the requirements of thesaid machines M and used in connection therewith with less inconvenience and with better results than in any other known way, adding much to the convenience and utility of said machines.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is as follows, to wit:

The within-described mode of using flywheels W in connection with portable or other machines M, Figs. l, 2, 4, and 6, when the said ily-wheels W are set to run within or loeneath the base B ot said machines M on antifriction roller-bearin gs G, or their equivalent,

purposes set forth.

JOEL BRYANT.

G, made as aforesaid, turns with the said.

substantially as herein described, and for the
